It depends if the cell in question is a prokaryotic or eukaryotic cell. In prokaryotic cells, the ribosomes are free in the cytoplasm as there are no membrane-bound organelles. In eukaryotic cells, the ribosomes are attached to the rough endoplasmic reticulum.

Which of these can be found both floating free in the cytoplasm and attached to a larger membrane?
organelles. mitochondria, cytoskeleton, Golgi complex, endoplasmic reticulum, lysosomes ribosomes etc.....
Why is cytoplasm a colloidal system?
Cytoplasm is a transluscent, viscous fluid It has many inorganic molecules like water, salts and various organic compounds like proteins, carbohydrates and lipids. There are also nucleoproteins, nucleic acids and several enzymes in it. The protein particles, carbohydrates and salts are hydrophilic while fat globules are hydrophobic.The viscosity of cytoplasm changes under the influence of tmperature. The suspended particles display Tyndall Effect.Cytoplasm also shows resistance to flow freely which keeps the particles/suspensions floating and not settling down due to gravitational pull.All these properties (common to colloids) prove the colloidal nature of the cytoplasm beyond doubt.
What is the inside content of cells called?
Everything inside a cell is not really one thing, but a bunch of parts. The substance that these parts are floating around in is the cytoplasm, but the core or center of a cell is the nucleus. The "powerhouse" of the cell is the mitochondria, etc. There are numerous parts to a cell, and it depends on if you are talking about a plant cell or an animal cell.
What exactly is a floating floor?
A floating floor is a type of flooring installation method where the individual floor planks or tiles are not directly attached to the subfloor. Instead, they are laid over an underlayment or subfloor without being secured to it. This allows the flooring to "float" on top of the subfloor, which can be concrete, plywood, or an existing floor. Key characteristics and features of a floating floor installation include: Interlocking Planks or Tiles: Floating floors typically consist of individual planks or tiles that have interlocking mechanisms or tongue-and-groove edges. These interlocking components hold the pieces together without the need for adhesive or nails. Underlayment: A layer of underlayment material is placed over the subfloor. This underlayment serves various purposes, including sound insulation, moisture protection, and creating a smooth and even surface for the floating flooring to sit on. No Glue or Nails: One of the defining characteristics of a floating floor is that it does not require adhesives or nails to attach it to the subfloor. The flooring pieces are held together by their interlocking design. Room for Expansion: Floating floors often include expansion gaps around the perimeter of the room to allow for natural expansion and contraction of the flooring material with changes in temperature and humidity. Ease of Installation: Floating floors are known for their ease of installation, making them suitable for DIY projects. They can be installed over a variety of subfloor types, including concrete, plywood, and existing flooring, provided the subfloor is properly prepared. Types of flooring commonly installed as floating floors include laminate flooring, luxury vinyl plank (LVP), engineered hardwood, and some types of cork or bamboo flooring. The specific installation method and requirements may vary depending on the type of flooring material being used. Floating floors are popular for their versatility, ease of installation, and the fact that they can often be installed without the need for adhesives or extensive subfloor preparation. They are commonly used in residential and commercial settings and are known for their flexibility and the ability to accommodate slight subfloor imperfections.
Parts of the animal and plant cells and their meaning?
Parts of an Animal Cell and their FunctionsCell Membrane: The cell membrane is the outer most part of the cell which encloses all the other cell organelles. The cell membrane function is to control the influx of the nutrients and minerals in and out of the cell.Cell Cytoplasm: Cytoplasm is supposed to be the matrix or gel like substance/fluid present inside the cell. It is mainly made up of water and protein material. The cytoplasm is the key site wherein all life processes occur. Read structure and functions of cytoplasm to know more on this cell organelle.Nucleus: Cell nucleus is supposed to be the brainor the control center of the cell and thus one of the most important animal cell parts. It contains the genetic material i.e. the DNA (Deoxyribonucleic acid) and the chromosomes. The DNA is made up of nucleotides which eventually help in protein formation by the process of transcription and translation.Nucleolus: Nucleolus is a dark stained area inside the nucleus mainly responsible for the protein formation using RNA (Ribonucleic acid).Nuclear Membrane: This is the porous, protective sheath that covers the nucleus which allows influx of substances and is one of the distinctive characteristics of an animal cell. Read more on nuclear membrane function.Nucleoplasm: This dense fluid inside the nucleus contains chromatin fibers, which condense to form chromosomes and genes which carry hereditary information.Mitochondria: Mitochondria are among the largest cell organelles also known as the engine house of the cells. Oxygen combines with glucose to form energy (ATP) required for metabolism and cellular activities in this organelle. It is an independent organelle having its own Mitochondrial DNA, RNA and ribosomes owing to self replication and duplication.Ribosomes: As I mentioned previously, protein synthesis (transcription and translation) takes place in ribosomes. These organelles could be bound to the endoplasmic reticulum or free floating in the cytoplasm.Lysosomes: These are membrane bound sacs containing enzymes needed to break down unnecessary parts of the cell for reuse. It mainly helps phagocytosis and promotes intracellular digestion.Centrosomes: These small organelles surrounded by the microtubules or the centrosphere, contain the centrioleswhich are responsible for the initiation of cell division.Endoplasmic Reticulum (ER): The animal cell model clearly suggests ER to be the second largest cell organelle after mitochondria since these form a series of interconnecting flattened tubular tunnels; rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The RER is mainly responsible for holding onto the proteins formed in the ribosomes, thus being rough in appearance.Golgi Apparatus: The proteins formed and bounded by the ER need to be processed so as to perform normal functions. Golgi, membranous sacs associated chiefly with the endoplasmic reticulum, do that to release the protein chains.Vacuoles: Smaller gas and membrane vacuoles filled with fluids and water are present in animal cells. Their main function is storage.Having got to know the various animal cell parts, I hope it's easy for you to understand an animal cell and its importance.
What organelle is considered a factory because it takes in raw materials and converts them to cell products that can be used by the cell?
This organelle, in short description, is known as a mitochondrion (singular), or mitochondria (plural).
Are ribosomes floating in the cytoplasm?
Yes. Ribosomes are found both freely floating and attached to the endoplasmic reticulum.
Are ribosomes floating freely in the cytoplasm?
Yes. Ribosomes are found both freely floating and attached to the endoplasmic reticulum.
What organelle in the cells cytoplasm makes protein for the cell?
RIBOSOMES (ribosomes are like little factories that make protein)
Are the ribosomes found floating freely in the cytoplasm?
Yes. Ribosomes are found both freely floating and attached to the endoplasmic reticulum.
What is found free-floating in the cytoplasm or attached to the endoplasmic reticulum?
They are the ribosomes. They synthesize proteins in cell
Are the found freely floating in the cytoplasm?
Ribosomes are found freely in the cell cytoplasm and they are also found attached to a membrane system called the RER.
What are found floating in the cytoplasm?
Ribosomes
Where do cells build their protein from?
Proteins are built at ribosomes, which may be free floating in the cytoplasm or attached to endoplasmic reticulum.
Are the major site of protein synthesis?
Ribosomes, which can either be attached to the rough endoplasmic reticulum or free floating in the cytoplasm.
Why are proteins made in the cytoplasm and not in the nucleus?
Ribosomes in the Cytoplasm are identical to ribosomes on the ER, correctly called the Rough Endoplasmic Reticulum (RER). Smooth Endoplasmic Reticulum (SER) extends throughout the Cytoplasm - without Ribosomes attached.
Which of these can be found both floating free in the cytoplasm and attached to a larger membrane?
organelles. mitochondria, cytoskeleton, Golgi complex, endoplasmic reticulum, lysosomes ribosomes etc.....
